Ok, apologies it was not clear to me from your opening email, where you 
were stuck. I incorrectly assumed it was an an earlier stage than you 
are, so my input was not useful to you.

I checked the source of `conffile.l` and it need already has to runes to 
include config.h where I would have assumed you needed to 
(https://salsa.debian.org/med-team/eegdev/-/blob/master/src/core/conffile.l#L24).

A bit of searching found the following flex upstream bug:

   * https://github.com/westes/flex/issues/564

Which seems related. Hopefully, it can help you.
